What is the mass of muon plus `(mu^(+))`?

Text Solution

AI Generated Solution

To find the mass of the muon plus (μ⁺), we can follow these steps: ### Step 1: Understand the mass of the electron The mass of the electron (mₑ) is approximately \(9.1 \times 10^{-31}\) kg. ### Step 2: Determine the mass of the muon The mass of the muon plus (μ⁺) is given as 207 times the mass of the electron. Therefore, we can express this mathematically as: \[ ...

What is the masss of pion plus (pi^(+)) ?

The muon (mu) is a subatomic particle of the lepton family which has same charge and magnetic behavioue as the electron, but has a different mass and is unstable, i.e. it disintegrates into other particles within microseconds after its creation. Here you will attempt to determine the mass of the muon using two rather different approaches. (a) the most common spontaneous disintegration reaction for the muon is: mu rarr e+bar(v)_(e)+v mu where bar(v)_(e) is the electron antineutrino and v_(mu) the muon neutrino. In a given experiment using a stationary muon, bar(v)_(e)+v mu , carried away a total energy of 2.000xx10^(-12) J , while the electron was moveing with a kinetic energy of 1.4846xx10^(-11) J . Determine the mass of the muon. (b) Many experiments have studied the spectroscopy of atoms that have captured a muon in place of an electron. These exotic atoms are formed in a variety of excited states. The transition from the third excited state to the first excited state of an atom consisiting of a ^(1)H nucleus and a muon attached it was observed at a wavelength of 2.615 nm . Determine the mass of the muon.

    A negatively charged muon (mass 207 times the mass of an electron) is captured in a Bohr’s orbit of high principal quantum number (n). The atom thus formed is called mesic atom. The muon in high energy state cascades down to lower orbits by emitting photons. (a) The emitted photons are X rays. Why? (b) Find the atomic number (Z) of a mu-mesic atom in which the orbit with n = 1 will just touch the nuclear surface. Assume that the nucleus has equal number of protons and neutrons.
