Neutrino Detection Using Lead Perchlorate
νx + 208 Pb ⇒ Pb + ν ′ x (NC) ⇓ Pb+ xγ + yn The number of neutrons emitted (0, 1, or 2) depends on the neutrino energy and whether the interaction is via the charged current (CC) or neutral current (NC). The nuclear physics of this system is described in Ref. [4]. A lead-based neutrino detector must have an appreciable density of Pb atoms and the capability of detecting the electrons, gammas an...
متن کاملLead Perchlorate as a Neutrino Detection Medium
Lead can be an ideal medium for the detection and study of neutrinos. Such a detector may be realized through the use of a lead perchlorate (Pb(ClO4)2 ) solution as a Cerenkov radiator. The basic physical properties of lead perchlorate solution are given and preparation of the solution for use in a Cerenkov detector is described. Results from investigations of light transmission in lead perchlo...
متن کاملObserving Nucleon Decay in Lead Perchlorate
Studies of nucleon decay (see, e.g., [1, 2, 3, 4, 5]) are among the most important in physics, in that they provide direct tests of fundamental theories of particle physics. The different particle theories make rather different predictions as to what the nucleon decay half-lives might be, and even which decay modes would be expected to dominate. Although a number of searches for nucleon decay h...
متن کاملDetection of lead ions using an electrochemical aptasensor
The aim of this research was to develop a simple, selective and sensitive aptasensor for detection of Pb2+ based on hairpin structure of complementary strand (CS) of aptamer (Apt). Screen printed carbon electrode (SPCE) was electrodeposited by gold nanoparticles to be used as the substrate for the immobilization of Apt-CS. Moreover, gold nanoparticles (AuNPs) and thionine were added to increase...
متن کاملSupernova Neutrino Detection
Astronomers expect that every 30 years or so, a massive star in our Galaxy will reach the end of its life. When the core of such a star collapses, it emits nearly all of the gravitational binding energy of a neutron star in the form of neutrinos, some Eb ∼ 3 × 10 53 ergs. Less than 1% of this energy is released in the form of kinetic energy and optically visible radiation. The remainder is radi...
