Dominant fragment ions were found to be H<jats:sup>+<\/jats:sup>, CH<jats:sub>2<\/jats:sub><jats:sup>+<\/jats:sup>, and Sn<jats:sup>+<\/jats:sup>. Subsequently, fragment ions were mass-selected. The mass spectrum of the selected ions indicated that only a single peak appeared at the mass number of 120 u, being suggestive of the presence of <jats:sup>120<\/jats:sup>Sn<jats:sup>+<\/jats:sup> ions. The ion energy was set at the range of 20\u2013100 eV. The Sn<jats:sup>+<\/jats:sup> ion beam was irradiated to a Si substrate, and a film was then found deposited on the substrate after the ion beam irradiation. An X-ray diffraction measurement showed that the film obtained was metallic Sn. Then, the Sn<jats:sup>+<\/jats:sup> ion beam was irradiated to a quartz crystal microbalance substrate. We found that most of the irradiated Sn<jats:sup>+<\/jats:sup> ions were adhered to the substrate, at the ion energy levels of 25 and 58 eV, producing the Sn film, whereas a 107 eV Sn<jats:sup>+<\/jats:sup> beam caused a significant proportion of Sn atoms in the film to detach from the substrate, probably due to sputtering.<\/jats:p>","DOI":"10.1371\/journal.pone.0253870","type":"journal-article","created":{"date-parts":[[2021,6,25]],"date-time":"2021-06-25T17:27:26Z","timestamp":1624642046000},"page":"e0253870","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":3,"title":["Identification of fragment ions produced by the decomposition of tetramethyltin and the production of low-energy Sn+ ion beam"],"prefix":"10.1371","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0614-6433","authenticated-orcid":true,"given":"Satoru","family":"Yoshimura","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Satoshi","family":"Sugimoto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takae","family":"Takeuchi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kensuke","family":"Murai","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masato","family":"Kiuchi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"340","published-online":{"date-parts":[[2021,6,25]]},"reference":[{"key":"pone.0253870.ref001","doi-asserted-by":"crossref","first-page":"208","DOI":"10.1016\/S0257-8972(94)80034-0","article-title":"Formation of iron film by ion beam deposition","volume":"65","author":"K Miyake","year":"1994","journal-title":"Surf.
