A new way of depositing thin targets of monolayer thickness for nuclear reaction analysis: A case of the 550 keV 13C 14N resonant nuclear reaction

We suggest a method by which the thinnest possible uniform isotopic targets may be produced in favourable cases, by bonding a monolayer to a diamond substrate, for use in nuclear level studies at maximum energy resolution. The need to deconvolve the target thickness contribution, or concern about its possible non-uniformity, fall away. We illustrate with a new measurement of the proton energy width of the C 13 ( p , γ ) N 14 resonance at 550 keV.
