Available in PDF, EPUB and Kindle. Book excerpt: The cross section for the $p(e,espprimepisp+)n, d(e,espprimepisp+)2n$ and $sp3He(e,espprimepisp+)sp3H$ reactions are calculated using a simple model with pion, nucleon and $Delta$-resonance degrees of freedom for the kinematical conditions used in a recent Saclay experiment. For the $d(e,espprimepisp+)2n$ reaction, final state interactions between the two outgoing neutrons are found to have a large effect. The calculated quenching of the $pisp+$ production cross section for the deuterium target is in agreement with that observed experimentally. It is predicted that due to the strong final state interactions in the singlet S state of the two neutrons, the $d(e,espprimepisp+)2n$ cross section can have a large dependence on the orientation of the deuteron spin. For the $sp3He(e,espprimepisp+)sp3H$ reaction, the quenching is predicted to be $sim$0.4 which is in agreement with the unpublished results of the Mainz experiment. The four important contributions to the quenching are identified as: (i) the finite size i.e., the form factor of the trinucleons, (ii) the spin-isospin correlations in the trinucleons, (iii) the finite range of the propagation of the struck proton, and (iv) the possible pion-nucleon final state interactions.

Available in PDF, EPUB and Kindle. Book excerpt: Triply differential cross sections for the reactions np --> np[pi]0 and np --> pp[pi]− have been measured at the WNR Facility of the Los Alamos Neutron Science Center at the Los Alamos National Laboratory. The measurements were made with a pulsed neutron beam with a continuous spectrum ranging from as low as a few MeV up to about 800 MeV, which covers the pion threshold energy of about 280 MeV and above, on a cryogenic liquid Hydrogen target. The two outgoing nucleons are detected in coincidence. Pure CsI crystals were used on one side of the beam (12,̊ 200,̊ 280)̊, whose pulse height information was used for energy determination of identified protons, and on the opposite side of the beam (12-̊ 32)̊, the neutrons or protons were observed in an array of organic scintillators with time of flight information. Measurement of'both nucleon energies, by the combination of the pulsed nature of the beam, times of flight and pulse height, completely determines the kinematics and allows the angular distribution of the unobserved pions to be extracted for both np --> np[pi]0 and np --> pp[pi]− actions.

Book excerpt: An “intriguing and accessible” (Publishers Weekly) interpretation of the life of Galileo Galilei, one of history’s greatest and most fascinating scientists, that sheds new light on his discoveries and how he was challenged by science deniers. “We really need this story now, because we’re living through the next chapter of science denial” (Bill McKibben). Galileo’s story may be more relevant today than ever before. At present, we face enormous crises—such as minimizing the dangers of climate change—because the science behind these threats is erroneously questioned or ignored. Galileo encountered this problem 400 years ago. His discoveries, based on careful observations and ingenious experiments, contradicted conventional wisdom and the teachings of the church at the time. Consequently, in a blatant assault on freedom of thought, his books were forbidden by church authorities. Astrophysicist and bestselling author Mario Livio draws on his own scientific expertise and uses his “gifts as a great storyteller” (The Washington Post) to provide a “refreshing perspective” (Booklist) into how Galileo reached his bold new conclusions about the cosmos and the laws of nature. A freethinker who followed the evidence wherever it led him, Galileo was one of the most significant figures behind the scientific revolution. He believed that every educated person should know science as well as literature, and insisted on reaching the widest audience possible, publishing his books in Italian rather than Latin. Galileo was put on trial with his life in the balance for refusing to renounce his scientific convictions. He remains a hero and inspiration to scientists and all of those who respect science—which, as Livio reminds us in this “admirably clear and concise” (The Times, London) book, remains threatened everyday.
