“…The extraction of the partial capture rates in the (µ − + 150 Sm) reaction is in progress. It has been proposed that the 82 Kr rates will be remeasured at the RCNP [31] negative muon beam (MuSIC, Osaka, Japan), with the MuSIC and UTM groups [32,33] in the near future.…”

HPGe detectors were used to make a precise measurement of the γ-ray spectrum produced following ordinary (non-radiative) capture of negative muons by natural Se, Kr, Cd and Sm. The measurement was repeated for isotopically-enriched 48 Ti, 76 Se, 82 Kr, 106 Cd and 150 Sm targets. By investigating energy and time distributions, the lifetime of negative muons in the different isotopes was deduced. A detailed analysis of the intensity of the γ-lines enabled the extraction of the relative yields of several daughter nuclei. The partial rates of (µ − , ν) capture to numerous excited levels of the 48 Sc, 76 As, 82 Br, 106 Ag and 150 Tc isotopes (considered to be virtual states of the intermediate odd-odd nuclei in the ββ decay of 48 Ca, 76 Ge, 82 Se, 106 Cd and 150 Nd, respectively) were also extracted. These rates are important as an experimental input for the theoretical calculation of the nuclear matrix elements in ββ decay.

Muon capture isotope production (MuCIP) using negative ordinary muon (µ) capture reactions (OMC) is used to efficiently produce various kinds of nuclear isotopes for both fundamental and applied science studies. The large capture probability of µ into a nucleus, together with the high intensity µ beam, make it possible to produce nuclear isotopes in the order of 10 9−10 per second depending on the muon beam intensity. Radioactive isotopes (RIs) produced by MuCIP are complementary to those produced by photon and neutron capture reactions and are used for various science and technology applications. MuCIP on Nat Mo by using the RCNP MuSIC µ beam is presented to demonstrate the feasibility of MuCIP. Nuclear isotopes produced by MuCIP are evaluated by using a pre-equilibrium (PEQ) and equilibrium (EQ) proton neutron emission model. Radioactive 99 Mo isotopes and the metastable 99m Tc isotopes, which are used extensively in medical science, are produced by MuCIP on Nat Mo and $

Muon disrupts AKT hydrogen bond network in cancer

A cancer microenvironment generates strong hydrogen bond network system by the positive feedback loops supporting cancer complexity and robustness. Such network functions through the AKT locus generating high entropic energy supporting cancer metastatic robustness. Charged lepton particle muon follows the rule of Bragg effect during a collision with hydrogen network in cancer cells. Muon beam dismantles hydrogen bond network in cancer by the muon‐catalyzed fusion, leading to apoptosis of cancer cells. Muon induces cumulative energy appearance on the hydrogen bond network in a cancer cell with its fast decay to an electron and two neutrinos. Thus, muon beam, muonic atom, muon neutrino shower, and electrons simultaneously cause fast neutralization of the AKT hydrogen bond network by the conversion of hydrogen into deuterium or helium, inactivating the hydrogen bond networks and inducing failure of cancer complexity and robustness with the disappearance of a malignant phenotype.
