text: In nuclear physics these methods are used to study properties of the nucleus itself.
  Methods for studies of the nucleus:
  * Gamma spectroscopy
  * Hypernuclear spectroscopy
  Methods for condensed matter studies:
  * Nuclear magnetic resonance (NMR)
  * Mössbauer spectroscopy
  * Perturbed angular correlation (PAC, TDPAC, PAC spectroscopy)
  * Muon spin spectroscopy
  * Nuclear orientation
  * Channeling
  * Nuclear reaction analysis
  * Nuclear quadrupole resonance (NQR)
  Methods for trace element analysis:
  * Neutron activation analysis (NAA)
  * Associated particle imaging (API)
