Measurements of low-energy (d,n) reactions for BNCT

Measurements of low-energy (d,n) reactions for BNCT. Boron Neutron Capture Therapy.

Neutron yields and energy spectra have been measured for various deuteron-induced reactions at low energy. Neutrons of energy > 100 keV emitted in the 9Be(d,n)10B, 12C(d,n)13N, and 13C(d,n)14N reactions at Ed= 1.5 MeV were detected at five angles by means of liquid scintillator detectors. While low-energy neutrons were observed in all studied reactions, only 13C(d,n)14N is characterized by a re...

Low Energy Nuclear Reactions

Character and Role of Theory Storms’ view of where and how low energy nuclear reactions (LENR) occur has been called a theory, so we begin with an examination of the character of a scientific theory. A compact summary about theory in any science is available in Wikipedia: “A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that ...

Boron Neutron Capture Therapy (BNCT) - Low-Energy Neutron Spectrometer for Neutron Field Characterization -∗)

Boron Neutron Capture Therapy (BNCT) is known to be a promising and new cancer therapy which can kill tumor cells suppressing damage to normal tissues. Recently, accelerator based neutron sources (ABNS) for BNCT are under development especially in Japan. For characterization of the neutron field, we carried out the series study concerning thermal/epi-thermal neutron spectrometry especially for ...

Modern theories of low-energy astrophysical reactions

We summarize recent ab initio studies of low-energy electroweak reactions of astrophysical interest, relevant for both big bang nucleosynthesis and solar neutrino production. The calculational methods include direct integration for np radiative and pp weak capture, correlated hyperspherical harmonics for reactions of A = 3, 4 nuclei, and variational Monte Carlo for A = 6, 7 nuclei. Realistic nu...
